Yes, it sounds like a bug.  It should take the mutex locally.

I'm working on tidying up vce v3 and came across the function



static int vce_v3_0_check_soft_reset(void *handle)



Which writes to the GRBM_GFX_INDEX but doesn't take the mutex around it.  Nor does the parent function in amdgpu_device.c which calls all of the check_soft_reset callbacks.



Is this a bug?
